ATM Shutter Mechanism Single Motor Cam Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated-teller machine shutter mechanisms have a complex structure due to separate driving sources for opening/closing and locking, leading to increased failure rates and production costs, and are prone to damage from interference during the closing process.
Innovation Solution
A simplified shutter mechanism that uses a single driving source, comprising a main body with a shutter, an opening/closing unit, a locking unit, and a driving unit, where the opening/closing and locking operations are simultaneously performed by a motor and cam mechanism, with springs for elastic support and sensors for interference detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate motors or solenoids are used for shutter opening/closing and locking operations, then the shutter can be securely locked, but the structure becomes complicated and production costs increase
Solution Approach 1:
The patent combines the shutter opening/closing operation and locking operation into a single integrated mechanism. The cam mechanism simultaneously controls both the shutter position and the locking state during one rotational cycle, eliminating the need for separate motors or solenoids while maintaining secure locking functionality
Solution Approach 2:
The single motor-driven cam mechanism performs multiple functions: it controls shutter opening, shutter closing, and locking/delocking operations. This multi-functional design reduces the number of components while achieving the same reliability as separate dedicated actuators
2Reliability
If separate motors or solenoids are used for shutter opening/closing and locking operations, then reliable control is achieved, but production costs increase
Solution Approach 1:
By merging the control functions into a single motor-cam system, the patent reduces the total number of components that need to be manufactured, assembled, and tested. This integration directly lowers production costs while maintaining control reliability through the precise mechanical geometry of the cam profile
3Extent of automation
If the shutter is closed by a motor-driven mechanism, then automated operation is achieved, but interference during closing can damage the driving source
Solution Approach 1:
The cam mechanism is designed with predetermined geometric profiles that control the timing and sequence of shutter movement and locking. This pre-programmed mechanical path prevents interference by ensuring the shutter is properly positioned and locked before full closure force is applied, and by providing mechanical guidance that prevents misalignment during automated operation

AI summary
A shutter mechanism of an automated-teller machine according to the present invention comprises a main body including a frame, a shutter slidably coupled to a front side of the frame, a first protrusion protruding inward on an inner lateral surface of the shutter, and a fixing member protruding on a side surface of the frame; an opening/closing means for opening and closing the shutter in response to an external signal; a locking unit for preventing the shutter from being opened by an external force without a separate signal; and a driving unit for simultaneously operating the opening/closing unit and the locking unit. Therefore, the present invention provides a shutter mechanism of an automated-teller machine, wherein a shutter-opening/closing operation and a shutter-locking operation can be simultaneously carried out using a single driving source, thereby simplifying its structure and also reducing its production costs, and interference that may occur while the shutter is being closed does not impose a load on the driving source, thereby preventing damage to and malfunction of the mechanism, reducing a failure rate and also maintaining a smooth operational state.
